Most people troll once they get support because
- It's the weakest role to carry from unless duo and partner is the ADC.
- 1 mistake from a support and the whole team rages/spams the ??????????????????
- having to protect some scrub 20-40 mins 24/7
- No $ , no Items, no dmg
- No glory if support saves their adc but takes the kill in the process the ADC AFK's
- The only player/role that has to ward but no one else does.
Overall most players play dumb champions or their best champions say " Garen - double adc(MF-Ashe) Yasuo because they don't trust a random in carrying the game but only themselves and honestly I don't blame them. It's solo Q and relying on a random person is mistake #1 in the good ole' "Get good and Carry" logic.
